Resizing FreeBSD slices

[Yani Karydis]

Hello,

Does anybody know if Partition Magic (floppy disk boot) can recognise and
resize UFS partitions?
Or any other tool can effectively reallocate space between slices (without
having to dump the slices and reinstall the OS)?

I'm running a FreeBSD 5.2 mail server and as a newbie managed to create a
very small /var slice which is running out of space fast!

Thanks and Regards,
Yani
